The looping of the template for the lagging strand enables a dimeric DNA polymerase III holoenzyme at the replication fork to synthesize both daughter strands. (Courtesy of A. Kornberg. From L. Stryer, Biochemistry, 4th ed.he 3â²âââ5â² exonuclease action of DNA polymerase III. Note that this exonuclease activity takes place at the 3â² end of the growing strand (and is therefore 3â²âââ5â²). The coordination of exonuclease activity with strand growth helps to explain why replication is in the 5â²âââ3â² direction.
